When Intel released its first Sandy Bridge-E processors this past November, it was expected that we'd see the first quad-core variant appear in February. Lo and behold, that has held true. The Core i7-3820 is a 3.6GHz offering that lobs off two cores and four threads. It shares its max Turbo frequency with the i7-3960X at 3.90GHz, and despite the drop of cores, it also shares the same TDP of 130W.
